Which of these does NOT have to be recorded in the accident book?

In the context of maintaining an accident book, it is essential to record specific details that contribute to a comprehensive understanding of workplace incidents. The nature of the injury, the time of the accident, and the location of the incident are all critical pieces of information that help in assessing risks, preventing future occurrences, and complying with health and safety regulations.

Recording the nature of the injury provides insight into the severity and type of incident, which can help identify patterns and areas for improvement in workplace safety protocols. Documenting the time of the accident is similarly crucial as it allows for analysis of when incidents occur most frequently, which can inform shifts in safety measures or staffing. The location of the incident plays a vital role in identifying hazardous areas that may require further attention.

On the other hand, the injured person's national insurance number is not typically considered necessary for recording in the accident book. While it may be pertinent for administrative purposes within an organization, particularly concerning payroll and benefits, it does not directly contribute to the understanding or investigation of the accident itself. Therefore, this specific information does not need to be recorded in the accident book as it does not aid in improving health and safety practices.
